New feature: Plugins about python-p2p-network

Ohw ... the old ways to implement the framework shall still be available ;), not breaking you code.

I was thinking about this. Maybe can implemented with middlewares like http frameworks. The middleware will intercepted the message or connection make something and pass to the next step. Can be implemented compression, encryption, encode and decoding objects (like blocks on blockchain).

Just like nodejs express framework or so. That sounds indeed interesting. I am now busy with experimenting with plugin framework. The plugins can interact on all the events that occur and are processed in the order that they have been added. It looks a bit like middleware solution.

I am now considering a design pattern for this according to http frameworks. Not yet found a solution other than the plugin I already implemented some how. However, with the plugins all plugins are executed. Within the HTTP frameworks if next() is not called, the process stops. That is also great for error handling.

The difference with HTTP framework is that also functionality to send specific message for instance. Discovery functionality for example. That can be implemented well using plugins. I am struggling how this could be done using the design pattern of the http framework.

Do you have any suggestions?
